BACKGROUND Field

The disclosure relates to a method, electronic device, and storage medium for displaying a charging state in start of charging.

Description of Related Art

Recently, the use of electronic devices that are easy to carry, such as smartphones, tablet personal computers (PCs), wearable devices, etc., has increased, and with the sharply increasing use of the electronic devices, research on high-performance batteries for lengthening a use time of the electronic devices has also been actively conducted. These electronic devices may be connected with various external electronic devices, and may receive power from or transmit power to an external electronic device.

Along with a consuming trend emphasizing design, in development of an electronic device, the design of a graphic object such as a visual element like a background, an icon, a widget, etc., displayed on a display has been considered important, together with the exterior design of the electronic device. Recently, in development of the electronic device considering the design of the graphic object, a technique for implementing the graphic object of the display of the electronic device naturally based on a user's sense has been developed.

Thus, the electronic device may provide various user interfaces for providing various functions to the user. As the user interfaces are diversified, it may be important to provide an aesthetic effect as well as convenience in interaction with the electronic device to the user.

At present, the electronic device is visually providing an alarm corresponding to charging to the user using an indicator region of the electronic device or a screen-on scheme in wired or wireless charging.

However, as high-speed charging is applied, the electronic device may provide rapid battery charging in wired or wireless charging. On the other hand, the electronic device is merely capable of providing a consistent experience, regardless of a current work state as well as a charging speed in charging. Therefore, there is a need for providing an interactive visual effect to avoid disturbing a user's work, while sufficiently guaranteeing an alarm regarding a charging state in start of charging, based on various states of the electronic device such as a screen-off state, an application execution state, etc.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

Hereinafter, referring to the accompanying drawings, a battery charging state will be described, and an electronic device having mounted thereon a battery and a charging device (or charger) that may be used to charge the electronic device will be described with reference to FIGS. 2, 3 and 4 . According to an embodiment of the present disclosure, a charger may largely use a wireless charging scheme, a scheme including an external electronic device capable of supplying power to the electronic device, and a wired charging scheme.

FIG. 2 is a diagram 200 illustrating an example state where an electronic device is placed on a charging pad for wireless charging, according to various embodiments of the present disclosure.

In FIG. 2 , the charger uses the wireless charging scheme, and as shown in FIG. 2 , when an electronic device 201 is placed on a charging pad 202, a screen notifying a charging state in start of charging may be displayed on the screen of the electronic device 201. The electronic device 201 may be cradled in the form of standing or being placed on the charging pad.

For example, in a case 200 a where the electronic device 201 is placed on the charging pad 202, the electronic device 201 may transfer a signal for requesting wireless charging to the charging pad 202. As the electronic device 201 receives a response to the signal from the charging pad 202, the electronic device 201 and the charging pad 202 may be connected as indicated by 200 b, and wireless charging for the electronic device 201 may be initiated. In this case, in start of wireless charging, a charging scheme between the electronic device and the charging pad may be determined, and accordingly, any one of normal charging, fast charging, or super-fast charging may be determined.

According to an embodiment of the present disclosure, a graphic object dynamically changing in association with a charging state in start of charging may be displayed on the screen of the electronic device 201. For example, a charging state including the determined charging scheme, an expected charging completion time, and a charging capacity may be displayed together with a graphic object.

FIG. 3 is a diagram 300 illustrating an example state where an external electronic device is placed on an electronic device for wireless charging, according to various embodiments of the present disclosure.

FIG. 3 illustrates a scheme in which an electronic device 301 supplies power to an external electronic device 302. As shown in FIG. 3 , the electronic device 301 may serve as a charging pad, and when the electronic device 301 is placed on the external electronic device 302, the external electronic device 302 may perform charging using the wireless charging scheme with the electronic device 301. The electronic device 301 may be a smartphone including a battery, and may include various electronic devices such as a laptop computer.

The external electronic device 302 may charge a battery of the external electronic device 302 at a first speed (or a normal speed or with a charging power of a first magnitude during a designated time) or at a second speed (or a high speed or with a charging power of a second magnitude during a designated time). The external electronic device 302 may supply required charging power according to a charging scheme (e.g., the normal charging scheme or the fast charging scheme) supportable in the external electronic device 302 by performing communication with the electronic device 301. For example, when the electronic device 301 is wirelessly connected to the external electronic device 302, power stored in the battery of the electronic device 301 may be supplied to the external electronic device 302.

The external electronic device 302 may have a smaller screen size than the electronic device 301, but may output a charging state through a user interface corresponding to the screen size of the external electronic device 302. For example, a graphic object dynamically changing with the charging scheme may be displayed on a circular display region of the external electronic device 302.

For example, for the fast charging scheme, a color, a brightness, and a color effect (e.g., a gradation effect or a flickering effect) of at least a portion of a graphic object related to charging may be displayed to change fast, in comparison to the normal charging scheme. Moreover, an animation effect of moving along the edge region of the circular display may be implemented. For example, an external electronic device such as a smart watch may have various shapes such as a circular shape, a rectangular shape, etc., and display a graphic object dynamically changing corresponding to a charging scheme on a display corresponding to various shapes, thereby allowing the user to feel a sense of speed for charging and to easily recognize various charging states.

FIG. 4 is a diagram 400 illustrating an example of an electronic device in charging with a connector, according to various embodiments of the disclosure. In FIG. 4 , the charger uses the wired charging scheme. As shown in FIG. 4 , for the wired charging scheme using a connector 407, charging may be initiated when the connector 407 is inserted, and the charging state may be displayed on a screen 407 of the electronic device 401 in insertion of the connector 407.

The connector 407 of the charger may include at least one of various forms such as a form in which the connector 407 includes a cable with a side electrically connectable with the electronic device 401 and the other side is provided as a code connectable with power, a form in which a cable is connected to an external electronic device capable of supplying power to supply power to the electronic device 401, etc. For example, a first-type charger (e.g., a travel adaptor (TA)) may be connected to the electronic device 401. According to an embodiment of the present disclosure, the first-type charger may include a charger capable of supporting super-fast charging for supplying a charging power of up to 45 W, and may supply high charging power when compared to other chargers including the wireless charging scheme.

According to an embodiment of the present disclosure, the electronic device 401 may output a charging screen corresponding to the charging scheme when the electronic device 401 is capable of supporting the charging scheme of the first-type charger. For example, the electronic device 401 may output a charging screen including information about a state of the battery. The electronic device 401 may output a screen 460 including indication information such as a charging state (e.g., a charging quantity), a type of the charger, connection or disconnection of the charger in association with battery charging, battery charging, etc.

According to various embodiments of the present disclosure, a graphic object related to charging may be output using different display schemes according to the charging scheme such as the normal charging scheme, the fast charging scheme, or the super-fast charging scheme. For example, in start of charging, a dynamic change of the graphic object may be output on the screen differently according to the charging scheme such as the normal charging scheme, the fast charging scheme, or the super-fast charging scheme. In this case, the user may feel a sense of speed according to the charging scheme, and thus may easily recognize the charging scheme.

FIG. 5 is a flowchart 500 illustrating example operation of an electronic device to display a charging state in start of charging, according to various embodiments of the disclosure.

Referring to FIG. 5 , the method may include operations 505 through 530. Steps/operations in the operation method may be performed by at least one of the electronic device (e.g., the electronic device 101 of FIG. 1 ) or at least one processor (e.g., the processor 120 of FIG. 1 ) of the electronic device. In an embodiment of the present disclosure, at least one of operations 505 through 530 may be omitted, an order of some of them may be changed, or other operations may be added.

In operation 505, the electronic device 101 may identify whether a charging event indicating start of charging occurs. When occurrence of the charging event is detected (505—yes), the electronic device 101 may identify a supportable charging scheme in operation 510. According to an embodiment of the present disclosure, the electronic device 101 may identify start of charging by communicating with a connected charger or detecting a designated event signal from the charger, and may identify charging-related information such as a type of charging such as wired charging or wireless charging, a charging scheme, etc. Thus, the electronic device 101 may start control related to battery charging. According to various embodiments of the present disclosure, the electronic device 101 may output a control signal to display a graphic object related to charging differently according to at least one of a charging scheme of the connected charger (e.g., a magnitude and a speed of charging power supplied by the charger), a battery charging state (e.g., a charging quantity) at the time of start of charging, or the like.

In response to occurrence of the charging event, the electronic device 101 may identify a state of the display 160 thereof in operation 515. According to various embodiments of the present disclosure, the state of the display 160 may include at least one of an AOD state, a screen-on state, an application execution state, or a power-off state. For example, the state of the display 160 may roughly include a wake-up state where the user may use a function of the electronic device 101 and a sleep state where the use by the user is awaited, and the wake-up state may include the screen-off state and the application execution screen.

The sleep state may include the screen-off state where the screen is turned off in a case of absence of a user input during a certain time, and the AOD state. In the sleep state, the electronic device 101 may deactivate various hardware modules and/or software modules included in the electronic device 101 or may be driven with minimum power to execute a designated function. For example, upon switchover to the sleep state, the display of the electronic device is turned off, through which information processing or computation based on a hardware module and/or a software module is suppressed, thereby improving the battery use time of the electronic device 101.

In operation 520, the electronic device 101 may identify whether the charging scheme is the first charging scheme or the second charging scheme. According to various embodiments of the present disclosure, the first charging scheme may support a first charging speed and the second charging scheme may support a second charging speed, in which the first charging speed may be higher than the second charging speed. While the first charging scheme supporting the first charging speed and the second charging scheme supporting the second charging speed have been described above as an example, the electronic device 101 may also identify whether the charging scheme is a third charging scheme supporting a third charging speed for a plurality of charging schemes supportable by the electronic device 101. Herein, the third charging speed may be lower than the second charging speed. For example, the first charging scheme may be referred to as the super-fast charging scheme, the second charging scheme may be referred to as the fast charging scheme, and the third charging scheme may be referred to as the normal charging scheme. For the electronic device 101 supporting the first charging scheme and the second charging scheme, the first charging scheme may be referred to as the fast charging scheme and the second charging scheme may be referred to as the normal charging scheme.

When the charging scheme is the first charging scheme, the electronic device 101 may display a graphic object using a first display scheme indicating the first charging scheme based on the state of the display 160, in operation 525.

On the other hand, when the charging scheme is the second charging scheme, the electronic device 101 may display the graphic object using a second display scheme indicating the second charging scheme based on the state of the display 160.

According to various embodiments of the present disclosure, the first display scheme may be a scheme in which at least one of a first movement speed related to the first charging scheme, a color of the graphic object, or a color effect of the graphic object changes, and the second display scheme may be a scheme in which at least one of a second movement speed related to the second charging scheme, the color of the graphic object, or the color effect of the graphic object changes.

For example, for the first charging scheme, a graphic object related to charging may be output to move at a first movement speed higher than a second movement speed of a graphic object related to charging for the second charging scheme, or may be output to show such an effect. The graphic object may have a higher brightness value than the periphery thereof and may have various shapes such as a circular shape, a rectangular shape, a triangular shape, and an arrow. A gradation effect may be added to the periphery of the graphic object. In this case, according to the first display scheme and the second display scheme, the graphic object may be displayed in a scheme in which different movement speeds are applied or a color effect such as a color, gradation, etc., changes.

According to an embodiment of the present disclosure, a color, a brightness, or a transparency of the graphic object may be changed by user's setting. For example, when the currently displayed screen is the application execution screen, a setting value such as a color, a brightness, or a transparency for a graphic object related to charging may be changed at a user-desired level for an effective notification of the graphic object, without disturbing a user's work. According to an embodiment of the present disclosure, change of setting of the graphic object may be preset, and alternatively, when the graphic object is displayed in start of charging, setting values may be changed corresponding to a direction in which the user touches and drags the graphic object.

Meanwhile, the electronic device 101 may differently output the graphic object based on the state of the display as well as the charging scheme.

According to an embodiment of the present disclosure, when the state of the display is any one of the screen-on state or the application execution state, the graphic object may be displayed overlappingly on the currently displayed screen. For example, based on various states of an electronic device such as a screen-off state or an application execution state, a notification regarding a charging state may be transparently displayed, overlappingly on a currently displayed screen, without covering the currently displayed screen.

According to an embodiment of the present disclosure, when the state of the display is the AOD state, the partial region of the display may be activated and the graphic object may be displayed on the activated partial region. As such, in the sleep state such as the AOD state or the screen-off state, the partial region of the display 160 may be activated and the graphic object regarding the charging state may be differently provided on the activated region using the charging scheme, thereby effectively providing the charging state with low power in the low-power state.

FIG. 6 is a flowchart 600 illustrating example operation of an electronic device to display a charging state in start of charging, according to various embodiments of the disclosure.

Referring to FIG. 6 , an operation method may include operations 605 through 640. Steps/operations in the operation method may be performed by at least one of the electronic device (e.g., the electronic device 101 of FIG. 1 ) or at least one processor (e.g., the processor 120 of FIG. 1 ) of the electronic device. In an embodiment of the present disclosure, at least one of operations 605 through 640 may be omitted, an order of some of them may be changed, or other operations may be added.

FIG. 6 is a flowchart illustrating a case where a graphic object related to charging is displayed based on a current display state of the electronic device 101 according to a display scheme indicating a charging scheme.

Referring to FIG. 6 , the electronic device 101 may identify whether a state of the display 160 thereof is the AOD state, in operation 605. When the display 160 is in the AOD state (605—Yes), the electronic device 101 may activate a partial region of the display 160 in operation 610 and output the graphic object on the activated region according to the display scheme indicating the charging scheme in operation 615.

Meanwhile, when the display 160 is not in the AOD state (605—No), the electronic device 101 may identify whether the display 160 is in the screen-off state in operation 620. When the display 160 is in the screen-off state (620—Yes), the electronic device 101 may turn on the entire display 160 in operation 625 and output the graphic object on the currently displayed screen according to the display scheme indicating the charging scheme in operation 630. On the other hand, when the display 160 is not in the screen-off state, e.g., in the screen-on state, in operation 620 (620—Yes), which means that the screen is already turned on, the display 160 may output the graphic object on the currently displayed screen according to the display scheme corresponding to the charging scheme in operation 630.

When the display 160 displays the graphic object on the activated partial region or output the graphic object on the currently displayed screen according to the AOD state, the electronic device 101 may identify whether a designated time has elapsed or an output stop request is received from the user, in operation 635. When the designated time has elapsed or the output stop request is received (635—Yes), the electronic device 101 may stop outputting the graphic object in operation 640.

According to an embodiment of the present disclosure, the electronic device may set a time to display the graphic object in start of charging to a time defined at the time of release of a product, but a duration of display of the graphic object may be set to a user-set time. For example, in a scheme in which a graphic object is displayed for three seconds in start of charging and then disappears, the display of the graphic object may be set to be maintained during a user-set time. According to an embodiment of the present disclosure, the display of the graphic object may be set to be maintained during charging in the power-off state. According to an embodiment of the present disclosure, when an input to remove the display of the graphic object is received before the elapse of a preset time or a user-set time during the display of the graphic object in start of charging, the display of the graphic object may be removed.

FIG. 7 is a diagram illustrating an example charging screen in start of charging in a power-off state, according to various embodiments of the disclosure.

Referring to FIG. 7 , in the power-off state, an electronic device 710 may display a graphic object 730 generated based on contents of a charging start event upon insertion of a connector 707 of the charger for wired charging or upon reception of a signal for wireless charging from the charger. In this case, the power-off state may be divided into a state where the power is off as the remaining battery capacity becomes 0% and the power is off as the user presses a power button long. As such, in the power-off state, power supply to all components including various hardware modules and/software modules included in the electronic device is stopped. In the power-off state, minimum power supply is possible to perform a designated limited function, such that an electronic device 720 may display a first image 730 related to charging and then identify charging-related information according to connection of the charger. For example, an electronic device 740 may display a second image 750 indicating the remaining battery capacity continuously from the first image 730 to allow identification of the remaining battery capacity, and display continuous images to which a color effect such as gradation is applied to dynamically display a charging state. When the user removes the connector 707, an image 770 corresponding to stop of charging may be displayed differently from charging. As such, when the display is in the power-off state, the charging state may be indicated by continuous displaying of a plurality of images. In this case, the plurality of images may be given different attribute information including a shape of an image, a color effect such as gradation or flickering, etc., to add a moving effect corresponding to the charging scheme.

FIG. 8 is a diagram illustrating an example charging screen in start of charging in an AOD state, according to various embodiments of the disclosure.

FIG. 8 illustrates the AOD state where preset information, e.g., a time, a date, an application object, and a notification may be displayed in a designated color using a preset pixel and the other pixels may be set in a designated color (e.g., black). For example, when the display is an organic light-emitting diode (OLED) panel, the other pixels may be off.

Such an AOD function is a function that displays required information at all times using a low-power processor even in the sleep mode state, and an electronic device 810 may display information such as a calendar, weather, the remaining battery capacity, a missing call, and an unconfirmed message as well as a clock image on a part of the display as an AOD screen according to a user's selection.

According to various embodiments of the present disclosure, in the AOD state, an electronic device 810 may display a graphic object 830 generated based on contents of a charging start event upon insertion of a connector 807 of the charger for wired charging or upon reception of a signal for wireless charging from the charger. According to an embodiment of the present disclosure, the at least one graphic object may be output using various display schemes corresponding to a charging scheme, such as an animation effect, an icon, etc. For example, as shown in FIG. 8 , an effect as if a circular graphic object 830 rotates may be output. In addition, a shadow surrounding the periphery of the graphic object 830 may be displayed differently, and an effect as if a part surrounding the peripheral region rotates may be output. To differentiate a sense of speed for charging, a color of the graphic object 830 may be output differently.

Whether the screen switches to the locked screen or home screen from the AOD screen may be determined according to user's setting, and when the locked screen is set to be displayed, the screen may switch to the home screen upon occurrence of a screen switch event (e.g., a touch input, a password input, a lock pattern input, etc.) in the locked screen.

FIG. 9 is a diagram illustrating an example charging screen in start of charging in a screen-locked state, according to various embodiments of the disclosure.

Referring to FIG. 9 , in the locked screen, an electronic device 910 may display a graphic object 930 generated based on contents of a charging start event corresponding to start of charging, upon insertion of a connector 907 of the charger for wired charging or upon reception of a signal for wireless charging from the charger. The locked screen may correspond to the sleep mode, in which at least some of various hardware modules and/or software modules included in the electronic device may be deactivated or may be driven with minimum power to execute a designated function. For example, upon switch to the sleep mode, a picture or video taking function may be deactivated and the processor may be configured to drive only a limited function of an application program upon switch to the sleep mode. In this way, information processing or computation based on a hardware module and/or a software module is suppressed, thereby improving the battery use time. In the sleep mode, the graphic object 930 may be displayed for a certain time overlappingly on the locked screen currently displayed, and then disappear.

FIG. 10 is a diagram illustrating an example charging screen in start of charging in a home screen state, according to various embodiments of the disclosure.

Referring to FIG. 10 , as an electronic device 1010 receives a signal generated from outside, for example, a charging-related signal or an event is generated inside upon insertion of a connector 1007 for charging into the electronic device 1010, an electronic device 1020 may display a graphic object 1030 generated based on a user interface indicating start of charging or details of a charging start event. According to an embodiment of the present disclosure, the electronic device 1020 may display the graphic object 1030 overlappingly on the application execution screen. In this case, not to cover the application execution screen, the other part than the graphic object 1030 may be transparently displayed.

For example, the graphic object 1030 may overlap on the application execution screen using a layer. Herein, the layer may be defined as a frame for arranging the graphic object 1030. For example, when a plurality of graphic objects are arranged in association with charging, a plurality of layers may be used. When multiple layers exist, the layers may be displayed overlappingly with each other by adjusting a transparency differently for each layer, and graphic objects included in the respective layers may notify the charging state variously. For example, FIG. 10 shows the circular graphic object 1030, but various charging-related objects such as an image, a text, etc., may be arranged in different positions.

According to various embodiments of the present disclosure, the AOD screen, the locked screen, and the home screen may be generated by different applications. An application generating the AOD screen will be referred to as a first application, an application displaying the locked screen will be referred to as a second application, and an application displaying the home screen 430 will be referred to as a third application. According to an embodiment of the present disclosure, the first application may be executed by a first processor (e.g., a display driver integrated circuit (IC)) driven with low power, and the second application and the third application may be executed by a second processor (e.g., an application processor).

FIG. 11 includes diagrams illustrating examples of a charging screen corresponding to a first charging scheme based on a display state according to various embodiments of the present disclosure, and FIG. 12 includes diagrams illustrating examples of a charging screen corresponding to a second charging scheme based on a display state according to various embodiments of the present disclosure.

FIG. 11 shows graphic objects 1115, 1125, and 1135 based on the first charging scheme in a screen-off state 1110, an AOD state 1120, and a locked screen 1130, respectively, and FIG. 12 shows graphic objects 1215, 1225, and 1235 based on the second charging scheme in a screen-off state 1210, an AOD state 1220, and a locked screen 1230, respectively. The first charging scheme and the second charging scheme may correspond to different charging speeds.

Thus, the graphic objects 1115, 1125, and 1135 in FIG. 11 and the graphic objects 1215, 1225, and 1235 in FIG. 12 may be output using different display schemes. For example, by applying different colors, moving speeds, and color effects to the graphic objects 1115, 1125, and 1135 in FIG. 11 and the graphic objects 1215, 1225, and 1235 in FIG. 12 , a sense of speed for charging may be implemented. For example, by adding a gradation effect to graphic objects or changing a tone, a brightness, and a chroma of a color of the graphic object, an effect of changing a speed may be expressed. For example, the sense of speed such as normal, fast, and super-fast may be expressed using a rotation speed of a region surrounding the graphic object, a color expressing high speed, etc. For example, the sense of speed may be expressed by expressing a color and a background color of the graphic object or a color surrounding the graphic object differently or flickering the graphic object.

FIG. 13 is a diagram illustrating an example charging screen capable of providing a text, according to various embodiments of the disclosure.

Referring to FIG. 13 , in the AOD state, an electronic device 1310 may display a graphic object 1330 generated based on contents of a charging start event upon insertion of a connector 1307 for wired charging or upon reception of a signal for wireless charging. According to an embodiment of the present disclosure, after an electronic device 1320 activates at least a part of the display in the AOD state, the electronic device 1320 may output a graphic object 1330 and a text 1340 in activated regions, respectively. Herein, the text 1340 may include a battery charging state (e.g., a charging quantity %), a charging type (e.g., wired or wireless), and the remaining time until full charging as details for indicating a charging state.

FIG. 14 is a diagram illustrating an example charging screen incapable of providing a text, according to various embodiments of the disclosure.

Referring to FIG. 14 , in the home screen state or the application execution screen, an electronic device 1410 may display a graphic object 1430 generated based on contents of a charging start event upon insertion of a connector 1407 for wired charging or upon reception of a signal for wireless charging. In this case, various objects such as a text guiding a charging state, together with the graphic object 1430 may be arranged on the home screen or the application execution screen of the electronic device 1420, but in FIG. 14 , application objects are arranged in a lower end of the display, such that a text region 1440 may be removed to avoid covering the application objects. That is, the text region 1440 may not be provided.

FIG. 15 is a diagram illustrating an example of notifying a charging state using an edge region of an electronic device, according to various embodiments of the disclosure.

Referring to FIG. 15 , according to an embodiment of the present disclosure, as an electronic device 1510 receives a signal generated from outside, for example, a charging-related signal or an event is generated inside upon insertion of a connector 1507 for charging into the electronic device 1510, an electronic device 1520 may display a graphic object generated based on a user interface indicating start of charging or details of a charging start event.

As shown in FIG. 15 , the electronic device 1520 may display a graphic object related to charging on a region 1540 of the display.

According to various embodiments of the present disclosure, a position and a display scheme for displaying a graphic object may change with a charging scheme and a display state of an electronic device (e.g., a screen-off state, a power-off state, an AOD state, an application execution state, or a locked state). For example, in the application execution state, a graphic object may be displayed along the edge region 1540 of the display.

According to an embodiment of the present disclosure, when the partial region of the display is used, a charging state may be indicated using a user interface as well as a graphic object. For example, the user interface may be displayed along the edge region 1540 of the display. The edge region may correspond to a part of the display adjacent to a housing of the electronic device, and the electronic device may include four edge regions corresponding to a top end, a bottom end, a left side, and a right side of the display.

According to an embodiment of the present disclosure, the user interface may show an effect of moving along an edge region of the display in start of charging. For example, an animation effect of moving along an edge region starting from a first edge region ending in a fourth edge region may be implemented. According to an embodiment of the present disclosure, the user interface or the graphic object may include various attribute information. The attribute information may include, for example, at least one of a form (e.g., a face, a line), a color (e.g., a tone, a brightness, a chroma, or a color effect (e.g., a gradation effect, a flickering effect), movement (e.g., movement using pixel value control, movement based on continuous displaying of a plurality of images, movement of a graphic object), a moving direction, a moving speed, or a duration of display.

According to an embodiment of the present disclosure, the graphic object may be displayed on the display using a display scheme in which at least one of the size of the graphic object, the text, a color of an edge light of the electronic device, or flickering of the edge light of the edge changes.

According to an embodiment of the present disclosure, a text 1530 guiding a charging state, together with the graphic object, may be displayed together on the display. In this case, to avoid covering the application execution screen, the charging state may be displayed using an edge region, and at the same time, the text 1530 may be displayed overlappingly. For example, for the first charging scheme, flickering of the edge light may be faster than the second charging scheme. Moreover, using different edge light colors, charging schemes may be displayed to be distinguished.

An electronic device according to various embodiments may be one of various types of electronic devices, according to various embodiments of the present disclosure. The electronic devices may include, for example, and without limitation, a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, a home appliance, or the like. According to an embodiment of the disclosure, the electronic devices are not limited to those described above.
